Look at [the file before this commit](https://github.com/mpscholten/Propel2/blob/333cc2b58b65e5db8537b17d4949f5baeecb4989/src/Propel/Generator/Behavior/Sortable/SortableBehaviorObjectBuilderModifier.php#L166) where you can see, that there are two return points but only the first one will be executed and the second one, therefore cannot be executed and is death code.
